.To @ZZ whom, it may concern,.-

Be it known that we, JAMES EDWARD PLATT, engineer, of Hartford Works, Oldham, in the county of Lancaster, England, and

WILLIAM HALL RICHARDSON, engineer, of Bank View, Derker, Oldham, in the countyof Lancaster, England, have invented certain new and useful Improvements in Carding- Engines, the same to be used in conjunction Io with the casings or casing placed underneath certain parts of carding-engines used forcarding cotton and other fibrous materials, of which the following is a specification, and for which We .have obtained Letters Patent of I5 Great Britain', No. 1,432, dated January 31,

Our invention relates to the casings placed underneath the cylinder and taker-in roller and to the casing placed underneath the cyl- 2o inder only ot' carding-engines used for carding cotton and other fibrous materials; and our invention consists in arrangements by means of which such casings may, in the firstcase, be adjusted relatively to the cylinder and taker-in roller, and in the second case to the cylinder only, more readily and with greater accuracy than heretofore.

Ourinvention also consists in arrangements for carrying the taker-in roller-knives, so that 3o when once adjusted they remain in correct working position in relation to the taker-in roller, although such taker-in roller may be moved in order to be adjusted nearer to or farther from the cylinder.

3 5 The drawings hereunto annexed show a method of carrying' our invention into effect.

Figure 1 is a side view showing so much of a oarding-engine as is requisite to illustrate our invention, and Figs. 2 and 3 are views show- 4o ying portions detached and in a position at right angles to that in which they are shown in Fig. l. Fig. 2 shows a'section'through the line B C. It also shows a side View of the bracket f, and how it supports the` parts e of the casing A. Fig. 3 shows a section through the line E E and shows how the plate q carries the bracket o". Fig. 4 is a plan showing the pedestal It, the shroud t, and part of the plate or bracket q; and Fig. 5 is asection 5o through line C O, showing the .pedestal u, shroud t, and the plate or bracket q. Fig. 6

is a sect-ion and side view through the line B C (see Fig. l) upon a larger scale; and Fig. 7, a front view, also upon a larger scale of the bracket f shown in Fig. l, and which is used for adjusting the part e of the casing A. Fig. 8 shows the screw j of the bracket f enlarged. Fig. 9 Shows the bracket q and how it is secured to the shroud t. Fig. lO is a Section through the line F F of Fig. 9. Fig. l1 6o is a view, partly in section, of the pedestal u. through the line G G of Fig. ,andillustrates the devices for adjusting the pedestal u.

Fig. l2 is an enlarged View of the taker-in roller c and shows the plate q, brackets r, 2, and 3, andportions of the under casing A.

At ct, Fig. l, is one of the side framings of a carding-engine, which supports one end of the main cylinder Z) andthe taker-in roller c. Beneath the taker-in roller c and the main 7o cylinder b is the casing A, provided, as usual, with bars or grids. One portion d of the casing A is situate'beneath the taker-in roller c and is made of a segment of a circle of somewhat greater diameter than that of the taker- 7 5 in roller c. The other portion cof the casing A is situate beneath the main cylinder b, and is also made of a segment of a circle of somewhat greater diameter than that of the Inain cylinder b. The part d, Fig. 12, of the casing 8o A, situate beneath the taker-in roller c, is formed with a iiange d', which lhas around hole in it to receive the supporting-stud 2a, secured to the adjustable bracket 2. VThebracket 2 is also provided with a slot 2C, through which 85 passes the screw 2b, by which it is secured to the plate or bracket q, and the part e ot' the casing A, situate beneath the mainoylinder l), is formed with a flange e', which has circular slots p, corresponding to the circle ofthe 9o flange e', (see Figs. l and 7,) cut into it to receive the supporting-studs n. The part e of the casing A, which is nearest the taker-in roller c, is Supported by the stud 3, passing through a hole of the same diameter as the stud 3, formed in the flange e. The stud 3 is secured to the adjustable bracket 3, which is provided Withslots 3d, through whichpass screws 3b, by which itis secured to the plate or bracket q. The stud 3, after passing roo through the iiange e', passes through a horizontal slot 3c, formed in the side frame a.. This slot, while permitting of the horizontal adjustment of the stud 3, prevents any movement in a vertical direction.

u, Fig. l1, is an ordinary adjustable pedestal mounted on the side frame a, which carries the end c of the taker-in roller c. u', Fig. l1, is a stud secured by a nut to the side frame ad* The end of this stud a is tapped to receive an adjusting-screw o. The screw IU passes through the lower part of the pedestal u and is connected thereto by means ot the collar o, fastened by a pin passing through the collar and the screw lu. The bolt u2, passing through a slot in the side frame a, secures the pedestal 'a to the side frame a. Then it is necessary to set or adjust the pedestal n, the bolt a2 is slackened and the screw o turned either to the right or left, according tothe direction in which the pedestal is required to be moved. Then the necessary adjustment has been made, the pedestal u is secured to the side frame ci by the bolt '11.2.

i, Figs. 9 and l0, is a shroud which covers the end of the taker-in roller c.

q, Figs. 0, 10, and 12, is a plate or bracket capable of being slid on the side fra-me a.

s and s', Fig. l2, are knives ordinarily einployed in conjunction with taker-in rollers.

fr is a bracket which carries the knives s s', and is provided with a setting-screw o" for adj usting the height of the lower knife The bracket o' is secured to the plate or bracket q by a screw r3 in a slot r2, which permits of its horizontal adjustment in relation to the bracket q.

f, Figs. l, 2, G, 7, and S, is an adjustable bracket for adjusting the part e of the casing A, and is secured tothe side framing ci by means of a threaded stud m. The portion (Z of the casing A and the portion c, as shown in Figs. 1 and l2, are formed in separate pieces; but a shoulder is formed on the exterior of the part c opposite the star i e2, (see Fig. 12,) to rest upon the adjacent end of the part d for the support ot the said part c, so that when the brackets 2 3 are secured to the plate or bracket q the said parts (Z and c are both supported by the said bracket q, and when the said bracket is adjusted the said parts will move together just as though they were made in one piece. The part d is hung at its rear end upon pins or projections extending from the bracket (l. Sometimes for convenience of carriage we make the part e in two pieces, which are hinged together at the part marked e3 and shown in Fig. l; or the parts (l and c may be formed in one piece or be fastened together so as to constitute one piece. The portion d of the casing A and that portion c of the casing A which is situated nearest to the taker-in roller c are secured to the plate or bracket q in the same manner, whether the casing Ais formed in one, two, or three pieces. By means ot the slot Se those parts of the casing A adjacent to the star :l: c2 are prevented from being set too high and so coming in contact with the wire of the cylinder and takerin roller c.

The casing A is supported near .its front end by the plates or brackets 2 and 3, Fig. 12, secured to the bracket q, and farther to the rear by adjustable brackets j'. One of such brackets f is shown in the detached views, Figs. 6 and 7 and partly in Fig. 8. Each of the brackets f is provided with a foundation part g, which is fixed to the side frame a by the threaded stud m. Mounted upon the foundation part g is a sliding part 7L, provided with a slot m', through which the end of the stud m passes, the slot m permitting the movement of the part 7L on the foundation part g. The part 71l carries the stud n, which, after passing through the opening o in the side frame a, tits into the slot p, formed in the flange e, and by which the part e of the casing A is supported and adjusted.

Upon the foundation part g. we form ribs g', which ribs g pass into grooves formed in the sliding part 71,. rlhe ribs g act as guides, which only permit the sliding part 7L to be moved lengthwise upon the foundation part g. The sliding part 7i is drilled and tapped at 7.' to receive an adj listing-screw 7' (see Fig. S) of a well-known type, the head oi which is formed with an annular groove to receive a forked lug g2, projecting from the foundation part g, and while allowing the screw j to be turned round prevents it from moving lengthwise. By turning the screw in one direction or the other the sliding part 7L will be moved upon the foundation part g, and the part e of the casing A will be moved nearer to or farther from the card-surface of the cylinder' l). Then the sliding part 7i has been adjusted into the required position by means of the screw j, it must be secured therein by means of a nut Z, screwing upon the stud fm. Instead of the brackets f being sccured to the outside of the side frame a, such brackets may be secured to the inside of the side frame a, and in such cases instead of each oi the studs n passing through an open-- ing o in the side frame a, such stud o1, will pass at once into one oi' the slots p, formed in one et the side flanges e of the portion e of the casing A, situate beneath the main cylinder b.

XVe prefer the above construction of the brackctf; but any kind of adjustable bracket may be used instead, so long as the bracket permits of a circumferential movement ol' the part e of the casing A` which will be hereinafter described.

(l, Figs. 9 and 10,1's a plate or bracket having at its upper edge a projecting flange q', by which it is supported upon the side frame ci. The plate or bracketq is held against the side frame ay by the lower part t2 ofthe shroud i.

t, Figs. 9 and 10, is a shroud for covering the end of the taker-in roller c. The boss t of the shroud z passes into the pedestal a and forms a bearing-for one end ol the taker-in ICO IIO

roller c, which passes through it. The cap of the pedestal u, Figs. t and 5, when screwed down on the boss of the shroud t secures the shroud in its proper position.

Upon the shroud t we form two projecting parts or lugs fw, Figs. 9 and l0. Upon the plate or bracket q we form lugs zr, which titY `between the lugs w on the shroud t.

By this means the plate or bracket q is connected to the shroud t, so that when the pedestal wandv the shroud t are moved nearer to or farther from the cylinder b the plate or bracket q will also be moved with them. The plate orlugs or projections formed on the plate Q.

The knife-bracket r, Figs. 3 and l2, which carries or supports one end of each of the knives s s, ordinarily employed in conjunction with taker-in rollers, is provided with a iiange which rests on the top of the bracket q, and is secured to the plate or bra-cket q by the screw r3, which passes through the slot r2. (See Fig. 12.)

For convenience of description we have hitherto only referred to parts situate at one side of the carding-engine; but it will be readily understood that where necessary like parts are employed on each side of the carding-engine. l

The taker-in roller c having been adj Listedl into the desired position relatively to the main cylinder l), we first adj ust the part e of the casing A which is nearest to the taker-in roller c by means of the bracket 8, which carries the stud 3, and which supports this part and especially adjusts the position of that part of the casingA which we have indicated by the star e2. We then, by means of the brackets f, which carry the studs n, that enter into the slots p, formed in the flange e of the casing A, adjust theother portions of the part e, so that the entire portion c of the casing A will be concentric or nearly concentric with the card-surface of the main cylinder Z). lVe then adjust the portion d of the casingA beneath the taker-in roller c by means of the supporting-bracket 2, which by means of the stud 2 regulates the position ot' the part d, so that such portion d of the casing A will be concentric or nearly concentric with the cardsurface of the taker-in roller c. The bracket 2 is then securely fastened to .the plate or bracket q by the screw 2b or other suitable means passing through the slot 2c, formed in the plates 2. proper working position. lVhen it becomes necessary, from the wear of the card-surfaces of the main cylinder b and taker-in roller c, to readj ust the position of the taker-in roller c relatively to the main cylinder b, the taker- `tion of the part d may also be The casing A will then be in` ,ing the pedestal u, as previously explained.

The movement of the pedestal 'it necessary for the adjustment of the taker-in roller c will cause the plate or bracket q, with the part d of the casingA, to be moved along'with the pedestal. This movement of the plate 0r bracket q by means of the plate 3 and stud 3 will cause that portion e of the casing A which is situated nearest the taker-in roller c to be moved nearer to the cylinder I), and will cause the portion, e of the casing A, whichis supported by the brackets f, to be slightly moved circumferentially around the main cylinder b, the slots p, formed through e', the side flanges acting as guides and so permitting' it to be moved; otherwise, it' it were not for the movement permitted by the slots p, the part e would buckle or bulge.:

Vhen desirable, the portion e beneath the main cylinder 1^/ maybe readjusted relatively to the card-surface of the main cylinder b by means of the brackets f and 3, and the posil adjusted relatively to the card-surface of the taker-in roller c by means of the brackets 2. The portion e beneath the main cylinder b and the portion cl beneath the taker-in roller c are prevented .from ymoving sidewise by the side frames a a of the carding-engine.

Instead of forming the slots p, as above described, in the side flanges e and providing each of the brackets f with a stud n, we may in some cases provide the side iianges e' with studs, each of which passes into a slot formed in one of the brackets f.

Wemount the adj ustable-knife-brackets r upon the plates or brackets q, as previously mentioned, and by means of the slot r2 in the bracket 0 adjust the' bracket fr' horizontally, so as to bring the knife s to its proper position. Ve then by means of the adjustingscrew fr adjust the knife s to its proper position. Owing to their connection with the pedestal a by means of the plate or bracket q when once adjusted, the knives s and s will remain in correct Working positions in relation to the taker-in roller c, although such taker-in roller c may be moved in order to be adjusted nearer to or farther from the cylinder b.

In some cases we dispense with the use of the part d of the casing A, in which case our invention is applied solely to the adjustment of the part e of the casing A beneath the main cylinder l).

What we claim is-A 1. The combination, with the main cylinder and taker-in roller of a carding-engine, ofthe parts d and e of the casing A, the pedestals u and screws 0, the shrouds t, with the projections or lugs fw, the plates or brackets q,
